2.3 Power Supply The power supply of the EZ864 G Terminal has to be a single voltage source of POWER 5V-30V capable of providing a peak during an active transmission. The EZ864 G Terminal is protected from supply voltage reversal. An internal fuse ensures an electrical safety according to EN60950-1. This fuse is not removable. A fast acting fuse 0.8A with melting is necessary to use with the EZ864 G at a 24V power supply system for vehicles. The power supply must be compliant with the EN60950 guidelines.

2.4 RS-232 Interface The serial interface of the EZ864 -G Terminal is intended for the communication between the GSM module and the host application. This RS-232 interface is a data and control interface for transmitting data, AT commands and providing multiplexed channels. EMC immunity complies with the vehicular environment requirements according to EN 301 489-7. The user interface of the EZ864 G Terminal is accessible from a Data Terminal Equipment DTE connected to the RS232 interface and it is managed by AT commands according to the GSM 07.07 and 07.05 specification and the supported commands are listed in the AT Commands Reference Guide.
